I thought that I did one on him. but anyway he was very prompt and showed up on time. Showed me exactly what what coming up on the scans and we talked about the route we would take to fix the problems. I had the PCV put in today so I guess we will wait and see if the car acts up again. I will call Jamahl to see what he wants to do.

I would tell friends about YourMechanic.com, but I would highly recommend Tyrone. He has been more the accommodating! He is very skilled at what he does, he's personable, and very reliable. I think I've found a long-term mechanic in him.

By far the best experience I have had when servicing a vehicle. I chose this company because of convenience, and will use again because of the outstanding service. Matthew was able to diagnose and correct my vehicles issue while parked in my driveway. He took the time to explain the issue and was extremely professional. I will definitely be referring him and this company to friends and look forward to using them in the future.

All about Oxygen Sensor Replacement

With each new model year, manufacturers are adding more oxygen sensors to better manage engine operation. Some high performance engines have an oxygen sensor for each cylinder as well as one for the rear of each catalytic convertor. The sensors are located either underneath the hood or underneath the car. The oxygen sensors are connected (screwed) to the exhaust pipe, either in front or back of the catalytic converter. The front (upstream) sensors measure the amount of oxygen in the exhaust system. The purpose of the front oxygen sensor(s) is to measure how rich or lean the gases are as the gases exit the combustion chamber. Depending upon whether the exhaust gas is lean (high in oxygen content) or rich (low in oxygen content), the amount of fuel entering the engine is adjusted by the engine management computer to try and maintain an ideal mixture that produces the lowest emissions output from the catalytic convertor.
Rear (downstream) sensors are located behind the catalytic converter. The purpose of the rear oxygen sensor(s) is to monitor the oxygen content of the exhaust gases leaving the catalytic convertor.
If one or more of the oxygen sensors are faulty, your car may not pass the emissions test. If you drive your car with a faulty oxygen sensor, you may get poor gas mileage and it can damage the catalytic converter.

Many oxygen sensors are damaged by leaking oil or coolant. If that is the case, the cause of that leak needs to be identified and repaired, or else the replacement oxygen sensor will be damaged as well.

New vehicles require specific oxygen sensors, and not the universal sensors that were common prior to 1996.

Your vehicle has multiple oxygen sensors, and they all help the car run optimally. The front sensors measure how much oxygen is in the exhaust stream to measure how rich or lean the gases leaving the gas chamber are. The rear sensors measure the oxygen content of the gases as they leave the catalytic converter. The oxygen sensors then relay this information to your vehicle’s electronic control unit, so that it can adjust as necessary. Because cars depend on an ideal fuel-to-air ratio to function optimally, the oxygen sensors are leaned on for engine performance. When your oxygen sensors fail your car will run less smoothly, get worse mileage, and have worse emissions.
